PYRALINE DESK PAD Filed Jan. 22, 1930 Charles quibellet' Patented May 3, 1932 UNITED STATES PATENT OFFICE PYRALINE DESK PAD Application filed January 22, 1930. Serial No. 422,642.

My desk pad has a transparent face formed of pyraline or similar cellulose material which is slightly spaced from the back of the pad, so that a pocket is formed between b the back and the face into which the me1norand a can be placed, which Will be protected from soiling, misplacement or loss, and will remain easily in view. The pad is not bulged by the insertion of these memoranda, if insci-ted singly, and the pyraline is readily re moved and replaced when scratched or dis colored, or has become opaque; and any permanent notation such as a trade-mark can be printed on the front face of the back and remain permanently in sight. The device has a neat and attractive appearance, is strong and cheap to make, and the pocket between the pyraline face and the back is, by the struc ture of my device, narrow enough to hold without clasplng tightly the memoranda inserted in it, and wide enough to allow the pyraline face to be made of a material sufficiently stiff to give a flat surface to the pad.

Fig. l is a plan view of the face of the pad.

Fig. 2 is an inverted section on line 22 of Fig. 1. Fig. 3 is a plan view of the back of the pad, and Fig. 4: is a section on line 44 of Fig. l.

The pad has as its foundation a stiff piece of card board 8. At two opposite sides of the foundation piece 8, are two spacers 1, 1, which can be made of paper, muslin, cellulose or textile material of any kind thick enough to space the pyraline face plate 3 slightly away from the base piece 8, forming a pocket d, between them into which memoranda such as ff. 5 or 9 can be inserted, where the spacers are absent. The inner lines of the spacer material 1, are indicated in Fig. 1, by the lines a, a. The spacer material is, in practice, turned over the ends of the foundation 8, and can be secured to it by pasting, gluing or other similar means. These strips can be of a contrasting appearance with the surface of the foundation piece 8, giving a pleasing finish to the pad, seen through the transparent face plate 3.

Retaining clamps 2, 2, 2, 2, at the corners of the pad, for holding the face plate at its 59 corners, are formed of a flexible material that can be glued or otherwise suitably secured to the foundation 8, very satisfactorily by turning the material over and gluing it to the back of the foundation 8. These parts 2, retain the transparent face plate 3. This II face plate 3 rests at its ends on the spacers 1, 1, the edges of this face plate being indicated by the lines marked 6, b, b, b. The plate 3, is therefore spaced from the foundation plate by the thickness of the material forming the strip 1, the space between the face plate 3 and the foundation 8 forming a pocket d. At any point on the edges of the pad where the spacer strip is not interposed between the face plate 3 and the foundation 8, the memoranda such as slips of paper or card 4, 5 and 9 may be inserted. These will enter readily. Ordinarily they would be inserted only partly, leaving a grip hold to extend beyond the edges of the face plate, and, most satisfactorily, not extend to the edge of the foundation 8. In furtherance of this purpose, I usually make the edges of the foundation eX- tend beyond the edges of the face plate 3. If any memorandum slip as 5, gets Wholly within the pocket (Z, it is usually readily shaken out. An inscription such as 6 can be stamped on the face of the foundation 8, and will appear through the transparent face plate 3.

The face plate 3, can be made of quite thick and rigid material (a great advantage as it preserves a firm and flat surface regardless of the positions of the memorandum slips beneath it) as an actual pocket is formed between it and the foundation 8, which latter also can be made rigid and firm, thus giving a decidedly attractive character to the device. There will be, if the device is well made, a tendency of the face plate 3, even when the pocket (Z, is empty, to separate slightly from the foundation 8, while both remain perfectly flat. The face plate can be changed by pulling it out from beneath the retaining clamps 2, 2, 2, 2, and inserting another in its place. The back is covered 95 by facing 7, the edges of which are indicated by the lines marked with the letters e, e, on Fig. 3.

I claim:

A desk pad comprising in combination, a

foundation, formed of a stiff piece of pasteboard, a transparent face, spacers, formed of flexible material positioned between the face and the foundation and glued to the latter, at the sides of the desk pad, and forming spacing strips extending along the sides only of the desk pad and between the said face and said foundation, whereby a permanent separation is maintained between the face and the foundation at the bottom of the desk pad, and clamps, of textile material, enclosing the corners of the desk padand binding the foundation to the face at the corners of the desk pad.
